Specification of Letters Patent.

RAZOR-STROI.

To all whom it may northern:

Be it known that I, MAURICE O. NIL- LIAMS, a citizen of the United States, rcsid: ing at Detroit, in the county of "Wayne, State of Michigan, have invented certain new and useful Improvements in Razor- Strops; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to strops especially adapted for stropping the blades of safety and other razors, and consists in the construction hereinafter more fully set forth and pointed out particularly in the claim.

The object of theinvention is to provide simple andeiiicient means for giving" to the razor blade a transverse movement across the strop as it is drawn longitiulinally thereof to heighten the abrasive action 0:]?

the strop upon the edge of the blade.

The above object is attained by the device illustrated in the accompanying drawing, in which Figure 1 is a, perspective view of my improved stropping device. Fig. 2 is a plan "view of the strep, showing the reversed curves therein in a plane transversely of the strep. Fig. is a fragmentary view in section through the strep and hladeholder. Fig. 4: is an enlarged fragmentary view in 'liorizontal section on line tie-ti of Fin. 3.

'lothose skilled in the art or stroppinp; razor blades, the importance ot a rill-awing stroke of the blade across the strap as it is moved longitudinally thereof, is well understood; such a stroke produciiu, a wip ling action upon the edge oi the blade, wlrerel'ay the edge is refined and made to possess a condition of smoothness essential to a perfect shave.

My invention comprehends means :lor air complishingthe above stated result, and the accompanying drawings forming apart of this specification, illustrate one mode ol. carrying; out my' invention.

Referring to the structure shown in the drawings by the characters of reference marked thereon, 1 designates a FllZI'OP, which is preferably made of leather, and which in form has the shape of a series of reverse bends or curves extending longrtudmally thereof, the bends in the opposite margins of the strep coinciding so as to maintain the strep of a uniform width; The degree of deflection which. these bends may be caused to assume from a straight line may he varied, as desired; it being only necessary to provide for suilicient transverse movement to attain the desired object; s

Mounted upon the strop and movable longitudinally thereof is a blnde-holder comprising the spring jaws 2 between which the blade 3 is adapted to be held during the operation of stropping, said blade-holder being carried on a rotatable shaft 4 journaled in the end pieces 5 of the blade-holder frame, the strep 1. passing between said end pleucs'ulul below an actuating roller 6 which is connected to the shaft 4. of the bladeholder to impart movement thereto by In urns oi the gears 7, as shown in Fig. 1. The strop is held against the lower side of the {lfildlflllll'lgl roller 6 by means of a pressure bar 8 urged upwardly by a suitable spring 9 confined between said bar and a portion oi. the Frame, whereby sullieient tlriction is createdbetween the pressure bar and the roller 3 to cause a rotation of said roller as the device is moved longitudinally of the strep, the rotation of the actuating roller (3 causing the blado-holdm' to swing, from side to side to successively carry the blade into contact with the surlace ot' the strep as the direction of movrauont oi the device is changed, in a manner well under stood in the art and described more completely in l rotters Patent l lo. 9531,5240 issued l rl ureh 8, ltlli). For the purpose ol? llltt' nipulatiug the stropping device, it is provided with a handle ll) suitably connected with, the Frame.

The inner tacos ol. the end pieces 5 are beveled or riuuuled, as shown at H, so as not to roughen or abrade the margins of the strep as the stroppingg; device is reeiprocated long]tudinally thereon, and to prevent unnecessary 'lriotion between said parts.

The end pieces 5 engage the oppositemargins ol' the strep which is oi a width to lie l'reelv between them, so that as the bladebolding Frame is drawn longitlulinally thereon, the reverse bends in the strop will dellect the blade-holder laterally from a straight course, causing the edge of the blade to slide transversely of the strop as it;

is drawn longitudinally thereof, whereby the abrasive action of the stropr upon the edge of the. blade is heightened byreason the str0p.- By dotted lines in Fig. 2 is illustrated the lateral deflection of. the bladeholder with respect to the strop,

as it is drawn lengthwise thereof;

Having thus fully set forth my invention,

,what I claim as new and desire tosecure by Letters Patent, is

Y an article of manufacture, a razor strop having in its marginal edges a series iof coinciding transversely disp'osed'reverse bends.

: In testimony whereof, I sign thisspecification in the presence of two witnesses.
